Irrigation - Water Management, Pollution and Alternative Strategies
Irrigated agriculture is the most significant user of fresh water in the world and, due to the large area occupied, is one of the major pollution sources for the water resources. This book comprises 12 chapters that cover different issues and problematics of irrigated agriculture: from water use in different irrigated systems to pollution generated by irrigated agriculture. Moreover, the book ...

Review of agricultural water management policies in Near East and North African Region in light of water scarcity
This paper explores the current debate about water management policies and the factors affecting their formulation and implementation in the arid and semi–arid zones of the Near East and North African Region (NENAR). In this context, relevant and significant experiences of other countries in the world facing similar challenges are also considered (Sachdeva, 2009). The literature pertaining ...

The Importance Pressure Management on Agricultural Irrigation Applications
Irrigation systems world wide are dependent on sound pressure management techniques which are normally incorporated at the design phase of the project. This holds true whether you are designing agricultural irrigation systems incorporating drip, micro spray, sprinkler or pivot systems and has similar ramifications for turf irrigation or even golf course irrigation systems. Automatic Control ...

Effects of wastewater irrigation on soil properties and turfgrass growth
Reuse of treated wastewater for turf irrigation is often viewed as one way to maximize existing urban water resources. The aim of this study is to evaluate the applicability of treated wastewater for turfgrass and assess the effects of continuous use of treated water on the soil and crop. Two turfgrass plots irrigated with drinking water and treated wastewater were monitored over a two-year ...

Seasonal ammonia losses from spray-irrigation with secondary-treated recycled water
This work examines ammonia volatilization associated with agricultural irrigation employing recycled water. Effluent from a secondary wastewater treatment plant was applied using a center pivot irrigation system on a 12 ha agricultural site in Palmdale, California. Irrigation water was captured in shallow pans and ammonia concentrations were quantified in four seasonal events. The average ammonia ...

Opportunities for saving and reallocating agricultural water to alleviate water scarcity
As water scarcity worsens globally, there is growing interest in finding ways to reduce water consumption, and for reallocating water savings to other uses including environmental restoration. Because irrigated agriculture is responsible for more than 90% of all consumptive water use in water-scarce regions, much attention is being focused on opportunities to save water on irrigated farms. At ...

Five benefits of agricultural smart irrigation
Population growth and an increase in irrigated agricultural land lead to a greater need for water and energy, at a time when global warming and rising greenhouse gas emissions are posing a real environmental challenge. In this context, the benefits of smart irrigation, i.e., using the exact amount of water needed for each crop, help to optimize this scarce resource. If we take a closer look at ...

Key Challenges for UK Irrigation in Agriculture
Irrigated agriculture is an integral part of the rural economy, but increasing water use creates several challenges, not least meeting the food demands of a growing population while using as little water as possible to save energy. In this article, we’ll look at the key challenges for UK irrigation in agriculture, to shed light on what the industry must do to preserve itself. ...

Water efficiency of agricultural production in China: regional comparison from 1999 to 2002
We apply stochastic frontier analysis (SFA) techniques to a provincial level data set to measure technical and water efficiency in China's agricultural production from 1999 to 2002. The determinants of the efficiencies are identified together with the physical determinant structure of the irrigation factor, which refers to the water use per irrigated land area. The study yields the following ...

Perceptions and practices of farmers towards the salinity problem: the case of Harran Plain, Turkey
The Harran region, located in the South-eastern part of Turkey, is facing an increasing salinity problem due to excessive and inefficient irrigation practices. In this paper, we survey 619 cotton producers in the region and analyse their perceptions and practices towards soil salinity. The survey results indicate that formal education and training are the central factors that determine the ...

Self-Cleaning Irrigation Water Filters
One of the critical components of successful agriculture is irrigation, which ensures that crops receive the water they need to thrive. However, using untreated or impure water for irrigation can have detrimental effects on crops and the environment. Self-cleaning irrigation water filters have emerged as a groundbreaking solution to this problem. The Importance of Self-Cleaning Irrigation Water ...

LCA of integrated orange production in the Comunidad Valenciana (Spain)
In order to perform an LCA of integrated orange production in the Comunidad Valenciana two representative areas were studied. The functional unit was 1 kg oranges at the farm gate. Eight scenarios were considered according to type of irrigation, the origin of water and the tillage practice. The production of agrochemicals, the production and use of energy in agriculture (for irrigation and ...

Irrigation Systems 101: What you need to know
In the perfect scenario everyone could rely on rainwater for their farming practices, but this is not always the case. This is why employing the right choice from the different irrigation systems available is crucial for agricultural success. Irrigation systems are basically an artificial way to provide water to fertile soil for agricultural purposes. Crop irrigation is necessary to overcome ...

Food and water insecurity: re-assessing the value of rainfed agriculture
ABSTRACTRainfed agriculture has potential to produce needed cereals for the growing populations of West and Central Asia even though rainfed agriculture is perceived as risky. The value of rainfed agriculture to produce competitively should be re-assessed. This requires the concerted efforts of farmers, researchers, and policy makers to work on the technical factors that determine agricultural ...

Irrigation water governance in practice: the case of the Canale Emiliano Romagnolo district, Italy
Irrigation is an essential element of agricultural production whose absence would create great economic hardship in many regions of the global South. Yet irrigated agriculture uses 70% of global fresh water withdrawals, putting major pressure on global water resources. Whilst much research has focused on technological solutions to improve irrigation efficiency, irrigation water ...

Irrigation water pricing policy for water demand and environmental management: a case study in the Weihe River basin
Irrigated agricultural production is the backbone of the Chinese agricultural sector, but the increasing demand for irrigation water, its inefficient utilization and overuse of chemical inputs, accompanied by the short supply of water resources have endangered the nation's agricultural and environmental sustainability. The Chinese government has proposed a water pricing policy with the ...

Analysis of the hydraulics of the irrigation canals of Otrar, Kazakhstan
Surveys of relic canals at the Oasis of Otrar in Kazakhstan have been used to re-construct patterns of agricultural water use for irrigation between AD700 and AD1500. Hydraulic simulation software was used to calculate the water carrying capacity of historical irrigation canal networks. An analysis of modern day irrigation systems has enabled the calibration of crop water use models and an ...

Estimating water use efficiencies for water management reform in Southern Alberta irrigated agriculture
Water use technical efficiency (WUTE) and three definitions of water use economic efficiency (WUEE) were estimated for the four river sub-basins that encompass the 13 irrigation districts in Southern Alberta over a 5-year period: 2004–08. The average level of WUTE varied from 3.5 to 6.2 Mt dam−3. The gross economic value of crop production varied from Canadian (C)$345 to ...
